Optical lens

The optical lens can ensure excellent image performance only when the optical aberration is reduced as much as possible. The focus of the center light and that of the ambient light are not collected at one point, generating aberration. The use of aspheric lenses can easily solve these problems, and it is even possible to accomplish this purpose without adding more lenses. As the number of lenses to use decreases, the overall cost can also be saved.ed.

  • – STOP RING : Mold for press descend control (controls lens thickness)n)

Aspheric Glass Lens Molding Process

Lens molding

Core-building type : Type to match the outer diameter / off-center core through the centering work

Non-core type (Volume molding): : Type to match the outer diameter / off-center core only through molding.
